The Ioniq 9 was unveiled on 20 November 2024 in Los Angeles, California, U.S.[2] Previously, its styling was previewed as a concept car called the Hyundai Seven Concept in November 2021.

At the end of its development program in early 2024, the model was renamed to Ioniq 9.

[3][4][5] Designed under a concept called 'Aerosthetic', the Ioniq 9 incorporates aerodynamically optimized design features, such as a dual-motion active air flap at the front, 3D-shaped underbody cover, and low-resistance tires, achieving a drag coefficient of 0.259 Cd (with digital side mirrors optional in some markets).

A Dynamic Body Care system with touch massage functionality and swiveling seats for second-row passengers are among the key interior offerings.

[8] Sales of the Ioniq 9 are planned to commence in South Korea and the United States in the first half of 2025, followed by Europe and other regions.
